一、docker

• 安装dockeryum install docker -y
• 启动dockerservice docker restart
• 开机自启动systemctl enable docker
• 配置全局docker快捷方式(无需再使用sudo)

# 查看状态
sudo service docker status
# ec2-user为当前账户登录名
sudo usermod -a -G docker ec2-user
# 这句不用加sudo
newgrp docker 

• 安装docker-compose

# 下载docker-compose包并移动至/usr/local/bin/
sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
# 执行权限
sudo chmod +x /usr/local/bin/docker-compose
# 软链
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

二、mysql

##、当yum安装失败时
##、配置mysql yum库并安装

1. 下载mysql5.7的yum源
   wget https://dev.mysql.com/get/mysql57-community-release-el6-11.noarch.rpm
2. 安装mysql5.7的yum源
   yum localinstall mysql57-community-release-el6-11.noarch.rpm
3. 查看yum是不是多了两个仓库,mysql-community-source.repo,mysql-community.repo
   
4. 移除原先安装的mysql服务
   yum remove mysql55 mysql55-common mysql55-libs mysql55-server
5. 开始安装yum install mysql-community-server -y 或 yum install mysql-server -y
   5*如果出现GPG check FAILED，追加参数–nogpgcheck绕过GPG验证
   
6. 启动sql服务service mysqld restart
7. 另一系统命令查看启动状态systemctl status mysqld
8. 获取mysql默认密码如用mysql -uroot -p是无需密码的，因为mysql会默认读取提供的密码
cat /var/log/mysqld.log | grep "A temporary password"
   
9. 修改mysql密码mysql_secure_installation
   
10. 再提供一个修改默认密码方式(9、10二选一)：进入数据库update变更并重启服务

mysql>update mysql.user set authentication_string=password("yourpassword") where user="root" and Host="localhost”;
mysql>flush privileges;
mysql>quit;
service mysqld restart

11. 进入数据库mysql -u root -p
    

三、nginx

yum install -y nginx

四、redis

yum install -y redis6

五、conda

• 安装

wget https://repo.anaconda.com/archive/Anaconda3-5.3.0-Linux-x86_64.sh
sh Anaconda3-5.3.0-Linux-x86_64.sh
# 按场景一直回车Enter|yes

• 查看cd /home/$hostname/是不是有anaconda3文件夹，记录此路径并追加到~/.bashrc
• 环境变量vim ~/.bashrc，文件末尾添加export PATH=$PATH:/home/$hostname/anaconda3/bin
• 生效source ~/.bashrc

六、sshguard

• 配置epel源curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
• 配置Centos-7源curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
• 查看目录ls /etc/yum.repos.d/下是不是多了两个repo仓库epel.repo、CentOS-Base.repo
• 安装yum install sshguard -y
• 准备sshguard启动配置文件cp /usr/share/doc/sshguard-2.4.2/examples/sshguard.conf.sample /etc/sshguard.conf
• 编辑修改配置文件vim /etc/sshguard.conf

BACKEND="/usr/libexec/sshguard/sshg-fw-firewalld"  # 需要安装防火墙firewalld
FILES="/var/log/secure"                            # touch创建文件secure
BLACKLIST_FILE=90:/etc/sshguard.blacklist
WHITELIST_FILE=/etc/sshguard.whitelist

• 自启动服务systemctl enable sshguard
• 启动systemctl start sshguard并查看状态systemctl status sshguard
